Technologies Used

Getting Started

Clone this repository and install pnpm.

  npm i -g pnpm

Client

Make a .env file in the root of the repository. Refer to .env.example for the environment variables required for the project. You need to set up two things to run the client:

1. A postgreSQL database. You could set up a free one on Heroku. Set the value of DATABASE_URL as the url of the hosted database.

2. A free Pinata account. Pinata stores all the NFT images and metadata. Create an account, generate an API key and set the values of PINATA_API_KEY and PINATA_API_SECRET respectively.

To run the development server:

  # install dependencies
  pnpm install

  # run the dev server
  pnpm dev

Smart Contract

The hardhat directory contains all the code pertaining to the smart contracts. If you wish to play around with the smart contract code, refer to NFT.sol. Before you compile and deploy the smart contract, make a .env file in the hardhat directory. You need to set up two things:

1. A free Alchemy account. The project uses Alchemy to interact with the Ropsten network and deploy contracts. Create an account on Alchemy, create a new project on the Ropsten network and set the value of ALCHEMY_API_URL as the alchemy project url. If you're stuck at this part, refer to this guide.

2. A MetaMask account. Your Ethereum account's private key is required to compile the contract using Hardhat. Set the value of PRIVATE_KEY.

To compile and deploy the smart contracts:

  # install dependencies
  pnpm install

  # compile the contract
  pnpm compile

  # deploy the contract
  pnpm deploy

The pnpm deploy command should log something like this on the console:

  Contract deployed to address: 0x1d2Cc2e0D387A04aD5111ee9Fd391110ddA0976F

Make sure to change NEXT_PUBLIC_CONTRACT_ADDRESS in .env to the address of the newly deployed contract.
